Alphonso Priya*, Satvekar Trupti and Ramaiya Mira

ABSTRACT

Tribolium castaneum Herbst a red flour borer beetle pest of stored grain in many regions of the world causing immense damage to food products including flour, cereals, pasta, biscuits, beans, and nuts. The insecticidal activity of different concentrations of carpel and seeds extracts of Zanthoxyulum rhetsa Roxb DC (Rutaceae) were tested for their efficacy using the Film residue method against a red flour beetle Tribolium castaneum Herbst. The results showed that the Methanolic extract of carpels Zanthoxylum rhetsa (Roxb) DC showed the highest (81%/1000ug/cm2) toxic effect followed by the Petroleum and Chloroform (78%/1000ug/cm2) and Aqueous extract (77%/1000ug/cm2) of carpels Zanthoxylum rhetsa (Roxb.) DC. The Methanolic extract of seeds Zanthoxylum rhetsa (Roxb) DC showed the highest (75%/1000ug/cm2) toxic effect followed by the Petroleum extract (73%/1000ug/cm2) and Ethanolic extract (66%/1000ug/cm2) of seeds Zanthoxylum rhetsa (Roxb.) DC. Among the solvents, the Methanol extracts showed more toxic effect than other extracts. Carpels and seeds extract of Zanthoxylum rhetsa (Roxb.)DC produced high incidence of mortality and reduced the rate of development resulting in reduction in their population exhibiting insecticidal activity to a promising level and can be opted as good alternatives to chemical pesticides.
